TIDA-00421: Cannot get an image from TIDA-00421 with the deserializer DS90UB960-Q1:

Hello Mahdi,

Firstly, welcome to E2E. We will be looking into your question and will update this post as we gather relevant data. I have some questions that should help this problem move forward:

• Would it be possible to upload your code again with comments so I can better understand what is happening?

• Do you happen to have the register sequence provided by the OEM? And if so could you upload that?

• Are you able to communicate to the serializer? If so then the problem is more then likely on the imager side of things.

Hello Taylor,

Thank you for your reply, I will answer you questions below :

• Would it be possible to upload your code again with comments so I can better understand what is happening?
  • You will find it in the attachment

• Do you happen to have the register sequence provided by the OEM? And if so could you upload that?
  • I cannot publish it as it's under NDA.

• Are you able to communicate to the serializer? If so then the problem is more then likely on the imager side of things.
  • Yes I'm able to communicate to the serializer.

Could you please send me the driver of the TIDA-00421 ? because I cannot find it in the TI VISION SDK ?

Thanks,

Kind regards,

Hello Mahdi,

So the files for the imager you're using in SDK are located in:

C:\PROCESSOR_SDK_VISION_03_08_00_00\ti_components\drivers\pdk_01_10_04_05\packages\ti\drv\vps\src\devices\ov10640

This may very well contain the files you need to get the imager up and running. Please let me know if that works.

Also while I'm here, could you upload a font/back photo of the TIDA-00421 board so I can see the connections and such? Thank you.

Hello Taylor,

Yes I tried the driver inside the ov10640, but it's for MIPI connection and not DVP.

The TI DS90UB913A supports only DVP configuration so the sensor cannot be in MIPI, that's why. Could you please check this issue ?

Here below the photos front and back of the TIDA-00421:

Thanks,

Best regards,

Mahdi,
